[ Upstream commit 22f35042 ] Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d8 ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports. We already had such a print for DP/eDP. v2: Improve the comment in the code a bit, note the port D change in the commit message Cc: Radoslav Duda <radosd@radosd.com> Tested-by:

[ Upstream commit 457c52d8 ] If the VBT says that a certain port should be eDP (and hence fused off from HDMI), but in reality it isn't, we need to try and acquire the HDMI connection instead. So only trust the VBT edp setting if we can connect to an eDP device on that port. Fixes: d2182a66 (drm/i915: Don't register HDMI connectors for eDP ports on VLV/CHV) References: https://bugs.freedesktop.org/show_bug.cgi?id=96288Signed-off-by:

[ Upstream commit 3f4c68cf ] Check for SMU RX local/remote faults along with SPU LINK status. Otherwise at times link is UP at our end but DOWN at link partner's side. Also due to an issue in BGX it's rarely seen that initialization doesn't happen properly and SMU RX reports faults with everything fine at SPU. This patch tries to reinitialize LMAC to fix it. Also fixed LMAC disable sequence to properly bring down link. Signed-off-by:

Reason: __btrfs_buffered_write should run cow write when no_cow impossible, and current code is designed with above logic. But check_can_nocow() have 2 type of return value(0 and <0) on can_not_no_cow, and current code only continue write on first case, the second case happened in doing subvolume.

The hang is because of a 3 way dead-lock: Process A holds the recovery mutex, and waits for eehd to complete. Process B holds the semaphore and waits for the recovery mutex. eehd waits for semaphore. The fix is to have Process B above release the semaphore before attempting to acquire the recovery mutex. This will allow eehd to proceed to completion. Signed-off-by:

[ Upstream commit 6a480a78 ] First of all, trying to open them r/w is idiocy; it's guaranteed to fail. Moreover, assigning ->f_pos and assuming that everything will work is blatantly broken - try that with e.g. tmpfs as underlying layer and watch the fireworks. There may be a non-trivial amount of state associated with current IO position, well beyond the numeric offset. Using the single struct file associated with underlying inode is really not a good idea; we ought to open one for each ecryptfs directory struct file. Additionally, file_operations both for directories and non-directories are full of pointless methods; non-directories should *not* have ->iterate(), directories should not have ->flush(), ->fasync() and ->splice_read().

[ Upstream commit dd4e17ab ] Recently, in commit 37cf4dc3 I forgot to check if the timeval being passed was actually a timespec (as is signaled with ADJ_NANO). This resulted in that patch breaking ADJ_SETOFFSET users who set ADJ_NANO, by rejecting valid timespecs that were compared with valid timeval ranges. This patch addresses this by checking for the ADJ_NANO flag and using the timepsec check instead in that case. Reported-by:

[ Upstream commit 37cf4dc3 ] For adjtimex()'s ADJ_SETOFFSET, make sure the tv_usec value is sane. We might multiply them later which can cause an overflow and undefined behavior. This patch introduces new helper functions to simplify the checking code and adds comments to clarify Orginally this patch was by Sasha Levin, but I've basically rewritten it, so he should get credit for finding the issue and I should get the blame for any mistakes made since.

[ Upstream commit 65376df5 ] Commit b7643757 ("procfs: mark thread stack correctly in proc/<pid>/maps") added [stack:TID] annotation to /proc/<pid>/maps. Finding the task of a stack VMA requires walking the entire thread list, turning this into quadratic behavior: a thousand threads means a thousand stacks, so the rendering of /proc/<pid>/maps needs to look at a million combinations. The cost is not in proportion to the usefulness as described in the patch. Drop the [stack:TID] annotation to make /proc/<pid>/maps (and /proc/<pid>/numa_maps) usable again for higher thread counts. The [stack] annotation inside /proc/<pid>/task/<tid>/maps is retained, as identifying the stack VMA there is an O(1) operation. Siddesh said: "The end users needed a way to identify thread stacks programmatically and there wasn't a way to do that. I'm afraid I no longer remember (or have access to the resources that would aid my memory since I changed employers) the details of their requirement. However, I did do this on my own time because I thought it was an interesting project for me and nobody really gave any feedback then as to its utility, so as far as I am concerned you could roll back the main thread maps information since the information is available in the thread-specific files" Signed-off-by:

When the lun_mode is switched to internal LUN the same value for host->max_channel is retained. This causes an unnecessary scan over the second port/channel. This fix alters the host->max_channel to 0 (1 port), if internal LUNs are configured and switches it back to 1 (2 ports) while going back to external LUNs. Signed-off-by:

[ Upstream commit 69eea95c ] DMA addresses returned from map_page() are calculated by using an iommu bitmap plus a start_dma offset. The size of this bitmap is based on the main memory size. If we have more than (4 TB - start_dma) main memory, the DMA address calculation will also produce addresses > 4 TB. Such addresses cannot be inserted in the 3-level DMA page table, instead the entries modulo 4 TB will be overwritten. Fix this by restricting the iommu bitmap size to (4 TB - start_dma). Also set zdev->end_dma to the actual end address of the usable range, instead of the theoretical maximum as reported by the hardware, which fixes a sanity check in dma_map() and also the IOMMU API domain geometry aperture calculation.
